The Ghost is a special enemy that appears in the mansion in Buried. They fly close to the ground and float towards the player in a speed slightly faster than an average Zombie, and slow down once the player aims at them. For every hit the Ghost gets on a player, 2000 points are subtracted from their points count. If the player is out of points, they will do damage akin to regular zombies. They seem to spawn infinitely until the player leaves the house in which they dwell; the large house and the maze behind it that contains the Pack-a-Punch Machine. It is advised that all players store their points in the Bank before entering the house, unless they wish to Pack-a-Punch.

Every four to five rounds, players can obtain a Random Perk Bottle power-up by entering the house when the lights are on. This will cause all zombies to disappear when a player enters and Ghosts will eventually drop the Perk Bottle once all players are outside and the last Ghost is killed. In co-op, when entering the mansion when the lights are on, multiple Ghosts spawn even outside of the mansion, targeting all players. The Ghosts spawn one at a time for each player, meaning there will be roughly four times as many when there are four players.

If the player gets a bullseye on the dartboard in the saloon behind the small white line with a Ballistic Knife, the saloon piano starts playing on its own. If the player gets to the mansion piano within approximately 90 seconds, the player will see a Ghost playing the piano. They can get a free perk, even after purchasing four, by tipping her 10 points.

The 'Ghost' is a floating woman with brunette hair and pale white skin. They are dressed in typical half mourning attire; a dark dress with a veil and capelet. If close enough, the player may notice that she has tears streaming down from her left eye. They have purple blood and they dissipate upon death. They seem to resemble ghosts more than zombies, unlike most prior enemies. At times, it is possible to hear them talk quietly, uttering phrases such as "This is my house." and "You do not belong here."
